Important Information
Here are some general tips and important points to keep in mind when setting up and using connections in TWM:
Regional Availability & VPN Usage:
Before setting up a connection, please verify that the services of the chosen exchange are available in your geographical region. If access is restricted, you may need to use a VPN (Virtual Private Network).
Copying API Keys and Secrets:
When copying your API keys and secret keys, be meticulous. Ensure that you do not accidentally include any extra spaces (whitespace) before or after the actual key strings, as this will cause authentication to fail.
Initial Historical Data Download:
The first time you request data for a specific trading instrument (e.g., a currency pair like BTC/USDT) through TWM, the software will attempt to download all available historical data for that instrument from the exchange. This happens regardless of the specific time period you initially request. Please allow this comprehensive first download to complete fully before proceeding with further actions or analysis for that instrument.
Type of API Keys (System-Generated vs. Self-Generated):
During the API key creation process on an exchange, you might be asked to choose between system-generated or self-generated (e.g., HMAC vs. Ed25519) API keys. For TWM's purposes, either type is generally acceptable unless specified otherwise for a particular exchange. For details on the differences between these key types, please refer to the information provided by the exchange itself during the creation process.
Naming Your API Keys:
It's good practice to assign a descriptive name to your API keys when you create them on the exchange. While the specific name doesn't affect TWM's functionality, it helps you identify the key for your personal records and management. Some exchanges may even require you to name the key before you can proceed. Always pay attention to prompts and hints in the exchange's user interface to ensure all required fields are completed.
Troubleshooting Connection Issues & API Key Expiry:
If a connection that was previously working suddenly fails, and you've already ruled out IP address filtering as the cause, check the API key configuration settings on the exchange's website. Some exchanges issue API keys that have an expiration date. If your key has expired, you will need to generate a new one.
Understanding Connection Behavior:
Connections without API Keys: If you set up a connection in TWM without entering an API key and secret, TWM will still attempt to connect to the exchange to access public data (like market data feeds). However, you will not be able to execute trades or retrieve private account information (like balances or positions).
Connections with Incorrect/Expired API Keys:
If you do provide API keys but they are incorrect (e.g., mistyped, contain extra spaces) or have expired, the connection will fail. TWM will typically display a generic error message such as "Check your credentials."
